VNDSHELBYCLEANENG DEV Application filed January 2l, 12322. Serial No. 530,775.

e specification, reference being` had ytherein to the acconipanying` drawings.

ln our pending application iiled Dec.'v 2"?, i921, Serial No. 525,182 there is disclosed a windshield cleaning device operated by a spring' inotor that is wound or placed in an operative condition by a key which inust be intermittently actuated, and result of i' the spring motor being,` placed in an opera- ".tor necessitated numerous turns or yactua-` tive condition, a wiping kor *scraping arin may ber released, tobe oscillated against the face of a shield or window, to scrape or otherwise remove snow, sleet rain and other rnatter which might accumulate thereon and obscure vision. The key of the spring inotions in order to place the spring inotor in lull" operative condition or conipletely wound, and now we r,have va windshield cleaning' device, which includes a spring; inotor and ineens by which the motor by one stroke oi the lever, may he placed in an operative condition tnlly'wonnd up.

wifi/'e' also have a windshield cleaningde- Vice wherein the operatingg inechanisni is niore conipactly arranged, and this niechanisni will be hereinafter specitically described and then claimed.

lleference will now be had to ing', wherein- Fig-ure 1 is a plan of a portion of windshield provided with the cleaning the ' vice, which is partly broken away and partly in section;

2 is a Vertical longitudinal sectional View of a windshield cleaning deyice;

3 is a horizontal sectional View taken on the line llllll ol' Fig. 2;

Fig. l is a Vertical cross sectional View of the device, taken on the line lV-.lV oi? Fig. 2, and y Fig. 5 is an enlarged horizontal sectional view of a governor forming part of thevdevice. y Y p ln the drawing. the reference numeral 1 f denotes a channel shaped support having;

top and bottom walls 2 and 3 respectively and end apertured lugs e, said lngsfbeing attached to a windshield traine 5 or otherr support hy screw holts 6 and nuts or other fastening ineens. iThe suoport l is inaintained against the ifi-aine o, as best shown in Fig. 1l, with 'thewalls 2 and 3 horizontally disposed.

Journaled in the wall 2, at one end there-n of, is a tubular 'winding arbor 8 4through which entends'a crank shaft 9 hauifra .4 1 1 i b 'l v crank end l() thereoi jour-narco in the wail 3 and at one eno of the winding arbor 8 is a sinall gear wheel 11, while the opposite end'thereot is a ratchet wheel 12. Meslnneil with the small wheel l1 is alarge gea wheel 13 rotatable on a post 1d carried byy the wall 2 and loose on the post le and ole-v tachably connected to the gear wheel `fiis a socket portion 15 of a crank 16, said vcrank having a Vsuitable handle 17. The Asocket portion l5 oi4 the crank 16 niay be held in vwith the gear wheel 13 by annt 18 or other fastening; ineans onr the upper end oit' the post crank 16 in an oi" one hundredand eighty degrecs the large n rotation and the shall gear wheel l1 a phirality oit r/Qitations, depending on the ratio ofteeth between "lie large and Sina-ll wheels. l 'Y Attached to the tuhnlai inding arbor 8 the inner end or convolution of a spiral bandspring 19 which has its outer endoi convolution attached to a post 2O connectin the walls 2 and 3 oi the support 1;

Qt S is a large spring pressed lil Fixed on the crank sl wheel 21 provided with. pawl 22 norme-l f wheel 12 of the tubular winding bor 8, as

estA shown in 3, and when the spring,` 19 is wound upA or placed in an `operative condition the spring pressed pewl re'- cedes over the ratchet wheel, but eventually engages the ratchet wheel so that clockwise rotation of the winding arbor 8, under the intlnence of 'the expansive orce of the spring,1 19 rotates the large gear wheel 2l. rlhis largije gear wheel ineshes with a sin-all gear wheel 28 integral with a large gear wheel 2li on shaft 25 supported by the walls 2 and 3, andthe large gear wheel ,24 meshes with a sinall gea-r wheel 26 on a governor shalt 27 supported by the walls 2 and 3. @n the upper end of the governor shaft 27 is a cross head 28 lprovided witi horizontally' disposed centrifugally actuated governor'arnis 29, said arms being,` retained .ear wheel 1.3 receives a heli in a retracted position by theretractile torce .of springs connecting said governor arms to a transverse pin 8l, carried by the governor shaft. The pivoted ends of the zgovprevent any excessive rotation of the gov-- ernor shaft 2? and consequently maintain a uniform or steady operation of the spring motor.

rllhe cran-lc end l0 or' thel shaft 9 is connected by a pitman Se to a bell crank pivoted on a depending, post, carried vby the bottom `wall 3 oi the support 1, and said bell cranlr has asegment gear 37 meshing with a beveled gear wheel 38 on an oscillatory shaft 39, jonrnaled in the .support l and a bearing d() on the wall 3, said wall being cnt away, as at ll to provide clearance Jr'or the beveled gear wheel 8S.

The. arm shaft 39 :itends through the windshield frame and. vis irovided with a detachable wiper arm Ll2 on which is monnteda suitable wiper or scraping'member normally' engaging the outer 'race `oi the pane of glass 44 mounted in the wind shield frame. ber may be of any well known for n adapted to remove rain, snow7 sleet or foreign matter from the ont-er face ofthe windshield.

Enclosing the spring motor and he greater part ot the mechanism just described a rectangular crisim.` and rear members being' suitablyk connected to therear edges` wall members 46, said rear wall of the top and bottom walls 2 and 3 respect'vely. The casifo; is heldin position relative to the walls 2 and B-by screws 47 entering; spacing members 48 and 499k the iiormer b ing between the top wall 2 and the top of. the casing l5 andthe latter bet veen the walls 2 and 3, best shown in Fig. 2. The top wall of the casingl5 has two openings 50 and l, the former providing,` clear-y ance -l'or the socket portion l5 of the crank 16, andthe latter providingclearance tor a stop or sind 52.l carried by the top well 27 and against which stop or stud the ycrank .i6 is normally held `by the spring motorx its onrdevice is now constructed the crank 16 is normally maintained the left hand end oit the casing l5 and said crank may The wiper or scraper mem-,r

vbe swung to the right hand end of the casingto wind np the spring-motor. As the spring motor causes the wiper or scraper member i3 to be oscillated or swung back and forth against the outer face of the windshield, the crank 16 is slowly swung and restored'to its normal position at the left hand end oit the casing.

Itis obvious that the crank 16 and the stud or stop 52 must be removed kwhen mounting or dismounting` the casing 45.

vlt is thought that the operation and ntil ity of our windshield cleaningdevice 'will be apparent without further description, and it is obvious that various vchanges may be maden'ithont departing from the scope of the appended claims.

yWhat we claim is :4'-

' l. A spring` motor adapted to operate a member, and means including,T a bell crank ooerated b said motor and seement Gear and beveled gear for transmitting power` l. fin v'operating mechanism comprising' top and bottom walls7 a spring motor between saidy walls, an arm shaft on the bottom wall, a member carried by said shaft, means below said bottom wall adapted to bc operated by said spring motor to oscillate said arm shaft, andmeans yabove said. top wall adapted to beswung to wind said spring motor. c

5. An operatingineohanisnii as in claim Il, and a governor between said top and bottoni walls controllingthe operation of said spring motor. y i
